Acetone, also known as propanone, is a volatile and flammable organic compound with the chemical formula (CH₃)₂CO. When combined with chlorine (Cl), acetone can form various compounds, including chloroacetone and dichloroacetone. The reaction between acetone and chlorine is a complex process, involving the substitution of hydrogen atoms in the acetone molecule with chlorine atoms. This reaction is often used in the production of various chemicals, such as pharmaceuticals, agrochemicals, and specialty chemicals.
Chemical Properties of Acetone with Chlorine
Acetone is a polar aprotic solvent, which means it can dissolve a wide range of compounds, including polar and nonpolar substances. When combined with chlorine, the resulting compounds exhibit different chemical properties, depending on the degree of chlorination. For example, chloroacetone is a colorless liquid with a pungent odor, while dichloroacetone is a yellowish liquid with a strong, irritating smell. The chemical properties of these compounds make them useful in various applications, such as the synthesis of pharmaceuticals, pesticides, and other specialty chemicals.
Reactions of Acetone with Chlorine
The reaction between acetone and chlorine can occur through various mechanisms, including radical substitution, nucleophilic substitution, and electrophilic substitution. The radical substitution reaction involves the formation of free radicals, which can lead to the substitution of hydrogen atoms in the acetone molecule with chlorine atoms. The nucleophilic substitution reaction involves the attack of a nucleophile, such as a chloride ion, on the acetone molecule, resulting in the substitution of a hydrogen atom with a chlorine atom. The electrophilic substitution reaction involves the attack of an electrophile, such as a chlorine molecule, on the acetone molecule, resulting in the substitution of a hydrogen atom with a chlorine atom.
| Compound | Chemical Formula | Boiling Point (°C) |
|---|---|---|
| Acetone | (CH₃)₂CO | 56.3 |
| Chloroacetone | CH₃COCH₂Cl | 118-120 |
| Dichloroacetone | CH₃COCHCl₂ | 174-176 |
Applications of Acetone with Chlorine
